如何将流读取器响应转换为类对象

我目前正在研究一些功能，使httppost然后得到响应。

下面是我目前正在使用的代码:

public string SubmitRequest(string postUrl, string contentType, string postValues)
    {
        var req = WebRequest.Create(postUrl);
        req.Method = "POST";
        req.ContentType = contentType;
        try
        {
            using (var reqStream = req.GetRequestStream())
            {
                var writer = new StreamWriter(reqStream);
                writer.WriteLine(postValues);
            }
            var resp = req.GetResponse();
            using (var respStream = resp.GetResponseStream())
            {
                var reader = new StreamReader(respStream);
                return reader.ReadToEnd().Trim();
            }
        }
        catch(WebException ex)
        {
            // do something here
        }
        return string.Empty;
    }

函数返回字符串格式的xml，例如:

<result>
  <code>Failed</code>
  <message>Duplicate Application</message>
</result>

这需要转换成一个类对象-但我不确定如何以正确的方式去做。

欢迎指教

//m is the string based xml representation of your object. Make sure there's something there
if (!string.IsNullOrWhiteSpace(m))
    {
        //Make a new XMLSerializer for the type of object being created
        var ser = new XmlSerializer(typeof(yourtype));
        //Deserialize and cast to your type of object
        var obj = (yourtype)ser.Deserialize(new StringReader(m));
        return obj ;
    }
